You might be wondering if you can use regular batteries in solar lights if your solar lights’ batteries are dead. Here is the answer.
There are numerous causes for solar lights to stop functioning. However, it often turns out that outdated batteries are the main offender. As cost-effective and environmentally friendly as solar light batteries are, they eventually lose their ability to hold a charge. As a result, the solar lights won’t operate as effectively as they should.
Batteries for solar lights should be changed at least once a year for optimal lighting. This raises the question: Can you use regular batteries in solar lights? Actually, no. The main reason regular batteries like alkaline-based batteries are a bad choice for solar lights is that they are made to be thrown away when they run out of power. The reaction between zinc metal and manganese dioxide provides energy for these batteries.
Let’s find out.
Can You Use Regular Batteries In Solar Lights?
The failure of solar lights can occur for a variety of reasons. But it turns out that worn-out batteries are the main offender in the majority of cases. As cost-effective and environmentally friendly as solar light batteries are, they eventually lose their ability to hold a charge. The solar lights won’t function as they should if that occurs.
Batteries for solar lights should be changed at least once a year for optimal lighting. This raises the question: Can solar lights be powered by regular batteries?
The quick response is no. Regular batteries, especially those with an alkaline base, are not suitable for solar lights because they are made to be thrown away once they run out of power.
Yes, by a long way. Solar lights may be powered temporarily by regular batteries. Generally speaking, you shouldn’t keep standard batteries inside your solar lights for longer than a week.
What Are the Dangers of Using Non-rechargeable Batteries in Solar Lights?
What are the risks associated with using non-rechargeable batteries in solar lights, then?
Permanent System Failure
Alkaline batteries are unable to store collected charge, which will cause charging issues and permanent system harm.
Regular batteries cannot be relied upon to operate smoothly because they are not made for solar lighting systems.
Corrosion of Terminals
Your solar lights’ battery terminals can corrode and rapidly drain regular batteries. As a result of corrosion, the battery’s connection to its terminals may become compromised, preventing the battery from supplying power to the light.
A warranty is provided with solar lights, and warranties are only valid if you follow the manufacturer’s terms and conditions. Using the incorrect battery in your solar system could void the warranty. Additionally, the warranty does not cover any damages brought on by incorrect battery usage.
Are Solar Light Batteries Different from Alkaline Batteries?
Power from the main sun is stored in solar light batteries. The panels’ photovoltaic arrays capture solar energy and transform it into direct current. The rechargeable batteries will then hold the current, allowing them to power the lamps at dusk.
However, the reaction between zinc metal and manganese dioxide provides the energy for alkaline batteries. You shouldn’t use them in your solar lights as they are not intended for charging.
As you make plans to purchase new rechargeable batteries, it is perfectly acceptable to use regular batteries for a few days. Know, however, that given their potential to result in a system failure that cannot be repaired, it is not worth the risk.
Which Types of Batteries Do Solar Lights Need?
No special batteries are required for solar lights to operate. NiCd (nickel-cadmium) or NiMH (nickel metal hydride) rechargeable batteries are the two types of batteries they use.
Finding a new replacement solar light battery shouldn’t be a problem because both batteries are sold in numerous nearby local stores. Additionally interchangeable, both of these batteries can be installed in any order.
I advise choosing NiMH batteries when it comes time to replace your solar light batteries. Let’s examine the advantages of modern NiMH batteries over their vintage NiCd counterparts.
NiCd Batteries Vs. NiMH Batteries
- Capacity: Compared to NiCd batteries, NiMH batteries have a noticeable capacity advantage. Compared to typical NiCd batteries, these batteries can store two times as much solar energy. They provide better illumination and longer output times as a result.
- Environmental Impact: Being free of harmful substances, NiMH batteries are environmentally friendly. They can therefore be thrown away without harming the environment. Cadmium, a dangerous substance, is present in NiCd batteries. They must therefore be properly disposed of.
- Memory effect: Rechargeable NiCd batteries experience something known as the memory effect. The next charge will be lower if the batteries are charged before they are completely empty.
They will eventually stop holding any charge if you keep charging them before they are completely discharged. This is referred to as the memory effect. The memory effect is not present in NiMH batteries.
How Long Do Rechargeable Batteries Last in Solar Lights?
Batteries that can be recharged will eventually run out of power. Even when the solar lights are not in use, you must make sure to charge your batteries at least every three to four months to ensure that they continue to function properly.
The lifespan of a typical rechargeable battery is typically between one and two years, but it can vary depending on the brand, quality, and type of battery. The brightness and efficiency of your lights should degrade during that time.
It’s probably time to swap out the rechargeable batteries once you notice that your solar lights’ brightness, charging capacity, and overall performance have significantly decreased.
Replacing your rechargeable batteries for a short time with regular alkaline batteries is an easy way to determine whether they need to be replaced and to ensure that the solar panels themselves are in good working order.
Place your solar panels in direct sunlight for a day while using regular batteries, and then turn on your solar lights in a dark room to test whether the regular batteries still function. You should buy new rechargeable batteries if the brightness of your lights returns to normal.
Remember to take out the alkaline batteries from your solar lights after use to avoid doing long-term harm to the battery terminal.
How Do You Charge Brand New Solar Lights?
Nowadays, the majority of solar lights include an on/off switch, which is very practical for things like storing your lights. But it’s advised to turn off the switch when you install a new light and leave your solar lights in the sun for a few days to charge.
As a result, the battery can be fully charged, extending the life of the solar lights and preventing battery discharge when the lights are first turned on.
How to Improve the Lifespan of Rechargeable Batteries?
The number of cycles through which solar batteries are used determines how long they will last. While lithium batteries offer almost 2000 cycles, lead acid batteries are predicted to last between 300 and 700 cycles. In other words, lithium-ion batteries have a lifespan of 2 to 3 years, while LiFePO4 batteries typically last for 5 to 6 years. Lead acid batteries are estimated to have a lifespan of about 3 to 5 years.
- Ensure that the manufacturer or dealer you buy your solar lights from is reputable. The battery’s manufacturer warranty must be strong.
- Installing your solar lights in a climate-controlled area will prevent high temperatures from adversely affecting the battery’s life cycle.
- Your solar batteries should not be kept indoors or left unused for an extended period of time because they are susceptible to damage if not charged and discharged frequently.
- Find out about the various solar battery types and the components of your solar lights.
- Maintaining clean solar panels will result in better lighting and longer battery life.
Conclusion: Can You Use Regular Batteries In Solar Lights?
Typically, solar lights are made to function with rechargeable batteries. The LEDs can be temporarily powered by regular batteries if NiMH or NiCd rechargeable batteries are out of reach.
To temporarily power your solar LEDs, you can use standard batteries. Take your time choosing the right battery option, however, to ensure the long-term performance of your solar lighting units. Otherwise, you may end up having to replace your entire solar lighting system due to damage from repeated battery usage.
What Batteries Can Be Used in Solar Lights?
The best battery for solar panels and solar lighting systems is almost always a lithium battery. Unlike lead-acid batteries, lithium batteries don’t need to be maintained frequently. It is convenient for users as a result. Only 500 to 800 charge-discharge cycles are typically tolerated by batteries.
Will Regular Rechargeable Batteries Work in a Solar Light?
The problem with regular rechargeable batteries is that they are not designed for solar lighting units. Rapid drain and corrosion will follow from this. It may be challenging for the battery to get to the light as a result of these issues. Solar lights will be harmed or lose their warranty if you use regular rechargeable batteries in them.
Why Do My Solar Lights Not Last Long?
Sometimes your lights just don’t last as long as they once did and this is typically caused by batteries dying. Depending on how well they were sized for the application, commercial solar lights should have batteries that last five to seven years.
